FIRST! A few things I forgot to mention, that I noticed when I edited the video. This is a big topic for PCB design as well! Especially at higher frequencies - and the same techniques apply. Your bare board PCB manufacture will happily, for a big bag of money, make your PCBs at a specified impedance (+/- some tolerance). You still need to keep the correct trace width and spacing to the ground plane though. For systems where you use the same wires for RX/TX you would put the parallel termination in both ends of the cable (RS485, CAN, etc ).

Nice demo. I attended a 4 day course on the practical considerations for this - what a long 4 days...

Thanks. Yeah, I could imagine :)

Really great and easy to understand video of the importance of current loop impedance and signal integrity for PCB layout considerations. All this has a huge impact on radiated and conducted EMC too, which for a commercial product is an essential consideration!

A nice demonstration :) What you could also have shown is twisting the wire (as per the wires in cat cables). I use a hand drill to twist quite long lengths of sensor wire pairs together, also do the same on power wires, it helps a lot of emitted and picked up EMI.

I don't think this would have any effect on signal reflections

I tried the same with a potmeter --> 1. No reflection on the scope to begin with 2. Changingg potmeter simply changes amplitude What could be wrong?

Fantastisk video, Takker mange gange :-) Rigtigt lækker demonstration, jeg har altid haft svært ved at forstå det der med terminering af data ledere, nu tror jeg nok jeg har fattet det. Hvis ikke du er flyttet langt væk fra hvor du boede før, så er der Hamday i Esbjerg, lørdag d. 4. maj 2019 kl 10:00, det er primært walkie talkie, men der er typisk også mulighed for at gøre nogle gode elektronik fund på loppemarkedet måleudstyr, komponenter og deslige. www.hamday.dk/

Water, as we know it on Earth, is not really correct comparison. It is rather air, gas or, if we want to be correct - ether.
